chapter 45 heavymineral sands of the atlantic and gulf a western zone is approximately 5500 m long and 1200 m wide, and contains the best ore grades, of up to 30% heavy minerals. a central zone is 5500 m long with a width from 244 to 850 m, averaging 500 m. the central zone contains concentrations of up to 10% heavy minerals that are consistent along strike.

heavy mineral sands ore deposits overviewthe grade of a typical heavy mineral sand ore deposit is usually low. within the 21st century, the lowest cutoff grades of heavy minerals, as a total heavy mineral (thm) concentrate from the bulk sand, in most ore deposits of this type is around 1% heavy minerals, although several are higher grade.
of this total heavy mineral concentrate (thm), the components are typically
zircon, from 1% of thm to upwards of 50% of thm,

ore the value of the metal an ore contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining. metal ores are generally oxides , sulfides , silicates , native metals such as copper , or noble metals such as gold .
